Abstract: 本発明は、第３世代移動通信システムにおけるＦ−ＤＰＣＨ（フラクショナル専用物理制御チャネル）の送信電力を制御する方法及び装置に係り、とりわけ、ソフトハンドオーバ中のユーザ機器によって有用なものである。。ユーザ機器は、複数の無線リンクのそれぞれで同一のＢＥＲを観測できないことがあり、それゆえ、ハンドオーバ中に、インナーループにおけるＳＩＲ目標値をユーザ機器がどのようにして導出するかについて提案されていない。そこで、ユーザ機器は、ハンドオーバ中のすべての無線リンクについてＴＰＣコマンド誤り率の最大重み付け関数となるようにＳＩＲの目標値を調整すべく、ＴＰＣコマンド誤り率Ｒを導出する。重み付け関数における重みの選択に応じてユーザ機器はＳＩＲ目標値を設定する。その際には、すべての無線リンクについてのそれらのＴＰＣ  ＢＥＲがネットワークによって設定されたＴＰＣ  ＢＥＲの目標値以下となるようにＳＩＲ目標値を設定する。ユーザ機器は、サービスを提供しているＨＳ−ＤＳＣＨについてだけＴＰＣ誤り率の目標値を満たすよう、重みを選択してもよい。
